摘要
本工作研究了碳化硅的掺杂量对化学镀Ni-P-SiC-PTFE(聚四氟乙烯)复合涂层的微观结构和力学性能的影响。利用扫描电子显微镜(SEM)、X射线衍射仪(XRD)、纳米压痕仪、HSR-2M摩擦磨损试验机分别对Ni-P-SiC-PTFE涂层的微观结构和力学性能进行表征和测试。结果表明:碳化硅掺杂对Ni-P-PTFE复合涂层的成分、微观结构和力学性能都具有较大的影响,当镀液中碳化硅浓度为1.5 g/L时,所得Ni-P-SiC-PTFE涂层中SiC含量最高,涂层硬度达到最大值8.4 GPa,且Ni-P-SiC-PTFE涂层表现出优异的耐磨性能。
The effects of SiC doping on the microstructure and mechanical properties of Ni-P-PTFE composite coatings were studied in this paper.The microstructure and mechanical properties of the coatings were investigated by scanning electron microscopy(SEM),X-ray diffraction(XRD),Nano-indenter,and HSR-2M friction wear testing machine,respectively.The results show that SiC doping has great influence on the composition,microstructure and mechanical properties of Ni-P-PTFE composite coating.When the SiC concentration is 1.5 g/L,the content of SiC in the Ni-P-SiC-PTFE composite coating is the highest,together with the highest hardness of 8.4 GPa,at the same time,Ni-P-SiC-PTFE composite coating obtained at this concentration exhibits better wear resistance than other concentrations.
